Maybe you're just more of a DC fan, where they try to shoehorn most of their characters into being dull, overly serious, and grimdark clones of Batman no matter what. Interestingly enough, also completely screwing up Batman himself left and right along the way. ("OMG, did you see him gun down everyone with those machineguns? So kewwwwwwlll! And watch him slowly stomp along and box everyone along the way, that's the World's Greatest Detective who was trained by master king fu assassins if ever there was one! Oh wait, crud, he said something that was probably supposed to be funny but fell flat, I hate this now! Superheroes have to be dark and grimy and boring!!!")
Okay, I may be a bit biased and disgruntled there, lol.
Anyway, my point is basically just that God forbid there be some fun movies or shows out there. Or even realize that some of them have been humorous practically since day one. To this day I can't even comprehend how people raged about She-Hulk breaking the fourth wall or being a comedy. Just... like.... what?
